Treasury Secretary Steven Mnuchin left little doubt Tuesday that the administration will reject a congressional request for President Donald Trump's tax returns by a self-imposed May 6 target for a "final decision," setting the stage for a legal battle that will test the limits of congressional oversight.

In a letter to House Oversight Committee Chairman Elijah Cummings, Jordan demanded answers about why the Maryland Democrat's execution of a nonpublic "Memorandum of Understanding" with Financial Services Chairwoman Maxine Waters, D-Calif., and House Intelligence Committee Chairman Adam Schiff, D-Calif., never came up with Republicans.

Jordan, the top Oversight Committee Republican, said the issue was never broached with GOP members until he found out.

Jordan revealed:

Cummings vowed to share House Oversight Committee information with Waters in the covert agreement, even though doing so could conflict with House rules. Jordan said the agreement with Waters stipulated Cummings would consult her before issuing a subpoena.

All these subpoenas and investigations are a corruption of government power. It is a perversion of the authority bestowed on these rotten elected representatives to use the force of government to personally attack a political adversary or to undermine the president for political gain. If you don't understand what kind of war has been waged by the Democrats, you aren't paying attention.

What about the people who gave the House of Representatives to the Democrats? What have the Democrats delivered? Not a damn thing.

You have to adjust for name recognition, though. Biden, at just south of 30 percent, is still something like a 2:1 underdog. And Bernie's position at 20 percent, as I wrote yesterday, is tenable but not great. pic.twitter.com/jwSd8Y2m77

I think we can discount a couple of major-ish contenders like Elizabeth Warren and Cory Booker. And the no-names who are running on ego (and the chance to raise money they can spend elsewhere) like Eric "Nuke the Gun Owners" Swalwell and... what's his name, the congressman from Massachusetts who just announced.

Other than that, wide open -- and that's why it's getting so nasty, so early.

Leftists harassed one of their own off the platform today for a project she worked on 10 years ago. She left citing death threats. If you’re mobbing someone because they don’t pass your purity test—maybe take a look in the mirror and ask yourself who’s the fascist. pic.twitter.com/5D5uIbKhlq

There is definitely something to be said about the halting nature of Biden's inchoate campaign. If he's this stumbling about merely getting into the race, how will the campaign he actually *runs* look like? https://t.co/8PZto4ZkFq

On Monday I wrote a column about changing politics in Ohio, effectively turning the former swing state solid red. It included this bit about the blue collar/culturally conservative voters which national Democrats have largely abandoned:

The last national Democrat I can think of who even knew how to speak the language of this bloc (even if he was disingenuous about it) was Bill Clinton. But Clinton is far too moderate for today's radicalized Dems. Can you imagine the "end welfare as we know it" Clinton of 1992 getting anywhere with next year's primary voters?

It didn't occur to me until hours after I'd published it, that maybe I should have included Joe Biden. It's just that I have what might be a real blind spot when it come to the former Veep. To me he comes across as so insincere, so phony, so unable to fake sincerity, that I just can't take him seriously enough for him to even ping the outer reach of my Serious Candidate Radar.

But on top of that, Biden is so clumsy at the basics of running a major campaign, that maybe I'm right to be so dismissive of him.
